The !FeaturePanel_Form widget is too complex and XML oriented to be easily implemented in the new PGSQLMapContextConfig driver. We'll leave it unsupported.

In its place, we'll use the !FeaturePanel_AttributeForm widget, as proposed in the following ticket : #183

known issue mentioned above was caused by : #188. Now fixed.
